Let's say you've got a bunch of entries in the "Original Generic Page" channel, which are getting replaced by pages with the same URLs in the "New Generic Page" channel. Assume also that entries are linked to one another in various ways (anchors in Wygwam fields; relationships via Playa fields, mainly).
For example, when the old "About" page (entry 5 in the Original Generic Page channel) is closed and replaced with the new one (entry 2000 in the New Generic Page channel), is there a good method for updating all of the other entries that previously referenced entry 5 to point to entry 2000 instead?
This change-over isn't happening all at once, and I suspect it'll be ongoing for quite a while as different channels/layouts are introduced over time.
We're using Structure and Publisher (site is multi-lingual) to possibly complicate things further.
Thoughts, any? Are there any add-ons that can help manage this?
